Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 2,253,475, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 2,253,475 | |
| -1 | -2,253,475 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,253,475.
Example:
1 x 2,253,475 = 2,253,475
and
-1 x -2,253,475 = 2,253,475
Notice both answers equal 2,253,475
With that explanation out of the way, let's continue. Next, we take the number 2,253,475 and divide it by 2:
2,253,475 ÷ 2 = 1,126,737.5
If the quotient is a whole number, then 2 and 1,126,737.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 2,253,475 | |
| -1 | -2,253,475 |
Now, we try dividing 2,253,475 by 3:
2,253,475 ÷ 3 = 751,158.3333
If the quotient is a whole number, then 3 and 751,158.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 2,253,475 | |
| -1 | -2,253,475 |
Let's try dividing by 4:
2,253,475 ÷ 4 = 563,368.75
If the quotient is a whole number, then 4 and 563,368.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 2,253,475 | |
| -1 | 2,253,475 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 79 | 163 | 175 | 395 | 553 | 815 | 1,141 | 1,975 | 2,765 | 4,075 | 5,705 | 12,877 | 13,825 | 28,525 | 64,385 | 90,139 | 321,925 | 450,695 | 2,253,475 |
| -1 | -5 | -7 | -25 | -35 | -79 | -163 | -175 | -395 | -553 | -815 | -1,141 | -1,975 | -2,765 | -4,075 | -5,705 | -12,877 | -13,825 | -28,525 | -64,385 | -90,139 | -321,925 | -450,695 | -2,253,475 |
